    • Love it!!!
Size: 1.01 Fl Oz (Pack of 1)
I was skeptical about buying this as so many other products didn't work that well. I have dry areas between my eyebrows and around my nose as I've gotten older. This stuff works GREAT!!! I felt the difference on the first day. It's been a couple weeks now. My face feels moisturized and it's not heavy or cakey. You don't need to use a lot. Most of the time I use my face cream on top of it, but even on days that I just go with this my face is perfectly fine and there hasn't been any dryness at all. One happy camper here. ... show more

    • My Morning Essential - The Science Actually Works! From a Franco-American - French Skincare aware!
Size: 1.69 Fl Oz (Pack of 1)
After using this regularly (I now buy the larger size), this has become my non-negotiable morning serum. My friends in France have been raving about this for years, and I finally understand why - it's a staple in French skincare routines for good reason. What sets this apart is the intelligent dual-hyaluronic acid formulation: the low-molecular-weight HA penetrates deeper layers to plump from within, while the high-molecular-weight HA creates a moisture-locking barrier on the surface. It's this combination that gives you both immediate hydration and long-term skin resilience. Plus, the madecassoside provides anti-inflammatory benefits while the B5 supports skin barrier repair. No questioning the quality here; La Roche-Posay's pharmaceutical background shows in the formulation precision. The texture absorbs beautifully, leaving no sticky residue, making it perfect for use under makeup or sunscreen. Worth every penny for the ingredient quality and consistent results. ... show more

I’m on my second bottle of the La Roche-Posay Hyalu B5 Serum and I absolutely love it! I use it every night, and it leaves my skin feeling hydrated, plump, and glowing. The hyaluronic acid in this formula is amazing, it absorbs beautifully and gives my skin that dewy, healthy look I adore. This serum has become a staple in my nighttime routine, and I’ll definitely keep ordering it. It’s gentle, effective, and makes a real difference. Highly recommend! ... show more

Size: 1.01 Fl Oz (Pack of 1)
Just ordering my second bottle. I usually do not post unless I am really impressed and I am really impressed. At 78 yrs. I have pretty much tried them all. I love this stuff and have put it on S&S. I use in the morning and at night. It’s not cheap but you get what you pay for.
